Solving
8100 + b2 = 900 + b

Solving for variable 'b'.

Reorder the terms:
8100 + -900 + -1b + b2 = 900 + b + -900 + -1b

Combine like terms: 8100 + -900 = 7200
7200 + -1b + b2 = 900 + b + -900 + -1b

Reorder the terms:
7200 + -1b + b2 = 900 + -900 + b + -1b

Combine like terms: 900 + -900 = 0
7200 + -1b + b2 = 0 + b + -1b
7200 + -1b + b2 = b + -1b

Combine like terms: b + -1b = 0
7200 + -1b + b2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-7200' to each side of the equation.
7200 + -1b + -7200 + b2 = 0 + -7200

Reorder the terms:
7200 + -7200 + -1b + b2 = 0 + -7200

Combine like terms: 7200 + -7200 = 0
0 + -1b + b2 = 0 + -7200
-1b + b2 = 0 + -7200

Combine like terms: 0 + -7200 = -7200
-1b + b2 = -7200

The b term is -1b.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1b + 0.25 + b2 = -7200 + 0.25

Reorder the terms:
0.25 + -1b + b2 = -7200 + 0.25

Combine like terms: -7200 + 0.25 = -7199.75
0.25 + -1b + b2 = -7199.75

Factor a perfect square on the left side:
(b + -0.5)(b + -0.5) = -7199.75

Can't calculate square root of the right side.
